Subject: [PATCH] leds: led-core: Get rid of enum led_brightness
This gets rid of enum led_brightness in the main led files,
because it is deprecated, and an int can be used instead,
or maybe even a uint8_t since it only goes up to 255.
Next we can also patch the other files to get rid of it completely.
